FirstEnergy Corp. (NYSE:FE) began installation Wednesday of $109 million high-efficiency rotors at its nuclear power plant outside of Cleveland, the Cleveland Plain Dealerreports.

The Akron-based energy company had ordered the rotors in 2008 to increase the 1,260-megawatt plant's output by another 30 megawatts.

The three rotors will spin at 1,800 rotations per minute, powering the Perry plant's main steam turbine, which produces electricity. Each rotor is 35 feet long and weighs about 175 tons, according to the Plain Dealer.
